A smudge of lipstick can be a telltale sign. It can link a victim or suspect to a crime scene or establish that two individuals came into physical contact during a crime. But investigators’ ways of telling lipsticks apart have limitations. Forensic scientists typically rely on techniques that are destructive or require human interpretation, such as energy-dispersive X-ray analysis or HPLC. A new report shows that Raman spectroscopy, in contrast, can distinguish the brand and . . .
